Yes - all good ideas!

For the Freight rail, Staten Island has recently restored it's freight rail link to New Jersey, but the rest of the four boroughs have the nearest link across the Hudson as Selkrik. One proposal that would change that would be to construct cross harbor freight rail tunnel for freight traffic.

And definitely more community gardens and roof gardens (green roofs).

Interesting quote I noticed in the enviornmental impact study for the cross harbor rail tunnel
"Although freight trains currently operate nationwide on diesel fuel, it is possible that electric freight trains may become more commonly used in the future."
At least they realize the possibility that there can be freight trains not operated by diesel. Especially now that diesel is getting expensive compared to electricity, and rail freight is getting ever more popular, making the case for electrification better and better.
